EZEKIEL VAN NOORDEN, OF BOSTON, MASSACHUSETTS.

DEVICE FOR OPERATING WINDOWS GR SHUTTERS.

To all 'whom t may concern:

Be it known that I, EZEKIEL VAN Noon- DEN, of Boston, in the county of Suffolk and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Devices for Operating Windows or Shutters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this speciication, in explaining its nature.

My invention relates to an improved device or mechanism for effecting the simultaneous control of a series or line of swinging sashes or shutters from a single point, the device or mechanism having also such adaptation that it will operate to hold the shutters or sashes closed or at any intermediate degree of closure or opening.

The object of my invention is to provide a mechanism or device of the above character that can be easily operated and the several parts of which will be so supported and operate in such manner and direction as to eliminate bending or distortion of the parts which would of course detract from the easy and proper operation Aof the, device.

My invention can best be seen and understood by reference to the drawings, in which- Figure l shows the device in side elevation. Fig. 2 shows the same in plan. Fig. 3 is a section on the line 3-*3 of Fig. l. Fig. 4 is a section on the line 4-4 of Fig. 1.

Referring to the drawings :*1 represents each of the several sashes of which two are shown for purposes of illustration.

2 represents the wall of the structure in which the sashes are placed. It will be assumed that the sashes below their pivotal point are adapted to swing outwardly to an open position, that is, outside the building or structure in which the sashes are placed.

Arranged within the building or structure and extending along by the sashes to be controlled on a line about parallel with the bottom of the sashes when in a closed position and some little distance removed therefrom is a frame 3. This frame consists of two parallelly-arranged spaced rails 4 fastened together by straps 5 extending transversely under the rails and fastened respectively thereto. These straps are attached to the rails at such intervals as will leave a clear runway or space between the Specicaton of Letters Patent.

respective rails and straps in front of each of the respective sashes and which space in lengt-h is substantially equal to the width of each one of the sashes.

The frame 3 is ixedly though pivotally supported to occupy or maintain a normal horizontal plane, assuming that the sashes when closed occupy a vertical position. The frame is supported by a series of brackets 6 which are secured to the wall of the building or structure in which the sashes are placed, beneath said sashes. Each of the brackets 6 is provided with a supporting headbar 7 horizontally arranged and extending outwardly beneath the rail 4 nearest to the sashes and to a point about midway between the two rails or center of the frame. From this point the headbar is continued by a hinged extension 8 which extends outwardly from the center of the frame beneath the rail 4 which lies farthest away from the respective sashes. The hinged extension 8 is secured to the bar 7 of the bracket by a hinge 9 upon the under side thereof. As many of these brackets are provided as is necessary to afford proper support and stability to the extended frame. The brackets are so arranged, however, that the headbars 7 and extensions 8 thereof will come beneath the straps 5 that tie the rails together, the extension 8 of each headbar being fastened to the strap beneath which it extends.

Arranged to slide longitudinally between the separate rails of the frame are what may be termed a series of carriers 10. These carriers are preferably circular in form with bodies about equal in diameter to the space between the rails so as to fit snugly therein and are provided with top and bottom flanges ll which extend over and under the respective rails, `he carriers having much of the aspect of grooved wheels, and are adapted to run on and between the respective rails. Two of these carriers are arranged in the space or runway in the frame in front of each of the several sashes.

Carried by each one of the carriers is a ring or clamp 12 which is secured to the carrier by means of a short shank 13 which extends through the carrier and is preferably loosely secured thereto in order that the carclamp 12 carried thereby is arranged to lie on the upper side of one of the carriers and on the lower side of the other with the effect that a line of rings will extend above the frame and a line below the same. Through these respective lines of rings or clamps extend rods 14 and 15, respectively, the clamps or rings being suitably affixed to the respective rods and movable therewith, for, as will be explained, the rods are adapted in the operation of the device to be movable longitudinally in opposite directions. rlhe rods extend, also, to a point beyond the line of the several sashes or to that point from which the sashes are to be controlled. There the respective rods are provided each with a rackbar 1G. Between these rackbars and in operative engagement with the teeth thereof a pinion 17 operated by a pulley 18 with the effect that as the pulley is turned in one direction or the other the rods 14 and 15 and carriers affixed thereto will be moved reversely in opposite directions, the respective carriers sliding within the frame. ln this connection, also, it is to be observed that the rods 1-1 and 15 are supported indirectly by the frame retaining the carriers and need no auxiliary support excepting that the rackhars and means for operating the same need such auxiliary support as is well known to those skilled in the art.

Pivotally secured to the shanks 13 of the rings or clamps connecting with the respective sets of carriers in the frame, in front of each of the several sashes, are bars 19. These bars extend inwardly in the direction of the sashes and cross one another in the manner of scissors, the bars being pivotally secured at their points of crossing or points 20 as shown. From these points or points of crossing the bars are extended to pivotally Connect with links 21 connecting with the opposite inner sides or faces of the respective sashes at a point near the bottom ends thereof. The links 21 are of some considerable length so that the bars 19 may be bent or curved in order that they may connect with the ends of 'the respective links.

The operation of the device is as follows: To open the sashes when closed the rods 14; and 15 are moved in opposite directions and in a mannerv whereby the carriers of each set of carriers retained by the frame 3 in front of each of the respective sashes, will be moved toward one another. This eect is obtained by turning the pulley and operating the pinion engaging the respective rack bars. As the carriers approach one another the crossbars 19 are extended, thereby exerting force upon the links 21 and opening the respective sashes,. yThe opening of the sashes continues until the respective carriers of each set are moved into contact or substantial contact with one another, which defines the full opening of the sashes. During this operation the resistance of the sashes to opening is borne by the frame 3, for during the opening of the sashes their resistance to such opening will cause the carriers to bear against the inside edge of the outer rail of the frame. 1t will also be noted that as the sashes open and the inclination thereof becomes changed, the lower' portion of the sashes to which the respective bars 19 are secured, through the links 21, will become elevated. These links, in other words, will assume a gradually increasing inclined position from their horizontal position when the sashes are closed. This is compensated for by the turning of the frame 3 which is allowed to turn and assume an inclined position through its hinged connection with the respective brackets supporting the same. To close t-he sashes the rods l-l and 15 are moved in opposite directions and; so that the carriers of each set in the frame are moved outwardly away from one another. This tends to open the bars 19 and tl'irough the links 21 to draw in the lower portion of the sashes closing` them. During this movement the resistance of the sashes to closing will cause the carriers to draw along the inside edge of the inner rail of the frame, or that nearest the sashes, and the frame will turn back and assume its normal horizontal position, when the sashes become fully closed. 1t is apparent of course that the sashes may be held in any partially open position depending upon the relative movement of the rods 14 and 15 and the corresponding relative positions of the carriers controlled by these rods.

Having thus fully described my invention, l claim and desire to secure by Letters Patent of the United States 1. The combination with a plurality of pivoted sashes, of a support extending alongside said sashes, means for mounting said support whereby it may turn about an axis, carriers arranged on said support and movable longitudinally thereon, means connecting with said carriers for edecting the simultaneous movement thereof on said support, and means whereby the force acting to move said carriers may be translated for opening and closing said sashes.
